An automatic closed loop drilling system is disclosed for providing automatic directional drilling capabilities in a bottomhole assembly. The drilling system includes at least one adjustable stabilizer that varies in response to formational and drilling conditions encountered downhole. A microcontroller is preprogrammed with a desired range of formation characteristics or with a desired inclination or target area. The microcontroller compares actual sensed data with the desired data and adjusts the position of the stabilizer blades to vary the direction of drilling.
